Basic troubleshooting
Press the power button to turn on the printer, and then attempt to do these initial steps to resolve the issue:
-
Make sure that the printer, supplies, and accessories are within the HP recommended temperature.
If the printer, supplies, and accessories are below the HP recommended
temperature, move the cold items to a warmer temperature. For temperature requirements of a printer, refer to the "Printer specifications" section in the User Guide.
Poznámka:
Temporary poor performance or print quality issues will occur if the printer is exposed to cold temperatures.
-
Close all printer trays and doors.
-
Allow the printer to be idle for approximately 20 to 30 minutes before attempting to print.
Varování:
Do not print when the printer is running a cleaning procedure.
Poznámka:

Print a Print Quality Report to identify the performance of each cartridge and print quality issue.
